Millot had attracted interest from major European clubs including Atletico, Tottenham and Galatasaray. Last season, he contributed 12 goals and eight assists across 43 appearances, playing a key role in Stuttgart's DFB-Pokal triumph. Atletico had viewed Millot as a major midfield reinforcement, but their failure to meet Stuttgart's terms led them to pursue Napoli's Giacomo Raspadori as an alternative. Stuttgart, meanwhile, plan to replace Millot with Arsenal's Fabio Vieira and has seen the transfer significantly boost their financial position given the premium from the Saudi deal.
